IMPROVEMENT IN HORSE-SHOES.

TO'ALL WHOM IT MAY CONCERN:

Be itknown that I, JAMES M. CUYKENDALL, of Metomen, in the county of Fond du Lac, and .Stato of Wisa oonsin, have invented a new and improved HorselShoc; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in-the art to make and use the same, reference being' had to the accompanying drawings', forming part of this speciiication.

The object of this invention is to facilitate the removal and renewal of the calks, while the shoe is onthe horses hoof, the shoe being of simple constructionpeasily made, and strong.

The invention consists in the manner of securing thelcalks to the shoe, which is done by securing a wedgeshaped dove-tail to the upper surface of the calks, said .dove-tails fitting into grooves arranged on the under side of the shoe, and which extend entirely across that portion of the shoe which is occupied by the calk. The dovetail form prevents lateral as well as upl-and-do'wn movements of the ca'lk, while the head of a screw, which is arranged in the side of the shoe,`and projects so as to cover part of the side of the calk, prevents backward motion of the latter, the tapering form of the dove-tail preventing a forward movement of the same.

By this arrangement the insertion or removal of the calks is greatly facilitated, especially as the screws lare inserted in the side of the shoe, and not in the bottom of the same, `which is the manner in which they` are generally arranged, whereby the headof the screw comes in contact withthe ground, and soon becomes so wornor battered that the screw ,can only be removed with great diiculty.

In the annexed drawing'my invention is illustrated- Fighre l being a bottom view of my improved horse-shoe.

Figure 2 is a similar view of tl1e-snme,'the calks being removed.

Figure 3 is a vertical sectional view taken through the centre ofthe shoe.

Figure 4 is a top view of the toe-calk C.

Similar letters ofreference .indicate like parts.

A is the horse shoe, made of malleable iron or any other suitable material. B B are the heel-calks, and C is the toe-calk. These calks may be made of cast steel, or of` Vany other suitable material.

The upper part of each heel-calk is provided with a-wcdge-shaped dove-tailtongue, which fits into a corresponding groeve, 6,'in the shoe, said groove extending entirely across that portion ofthe shoe where the'calk is attached, as shown in iig. 2. The dove-tail ealks are made to slide laterally within the grooves, thus allowing the calks to be`inserted or removed at pleasure.

The toe-calli C is also provided with` a wedge-shaped dove-tailed tongue or tenen, a', and the front portion oi' the shoe is provided with a corresponding groove, 6,', but the tenone' is provided with a groove, c, across its centre, and the groove t with a corresponding tapering projection, n?, as shown in the drawing.

All the calks are held in place within their grooves bymeans of screw-plugs D, which enter the shoe laterally, and have their heads conntersunk, partly in the .shoe and partly in the calli, as shown.

The extra tcnon el on the shoe, in thel centre oi' the groove b', is for the vpurpose of making that portion of the shoethick enough to allow of the insertion of the screw, and' also te afford protection for the head of the screw, without making the shoe too thick at the toe.

v In `order'to remove a calli, when it is worn or needs sharpening, it is only necessary to unscrcw its screws plug D, when the cn'lk can be removed and repaired, or a newbne substituted in its place, as may be desired.

By inserting the screw D, the calkis firmly held again in its place.

What I claim as` new, and desire to secure by Letters Patent, is-

1. Inserting the screws-D into the side of the shoe, directly beneath the calks, in su-ch a manner that the heads of the screws bind upon the celks, and secure them in place, substantially as herein shown and described.

2. The groove c, in the centre of. the tenen a of the toe-calk'G, in combination with the tenon cZ in the groove 6', and with the screw D, all made and arranged substantiallyns and for the purposes herein shown and described.
